Super Bowl LIV kicks off at 6:30 p.m. Sunday with the Kansas City Chiefs taking on the San Francisco 49ers.

Among the many festivities and activities that crop up around the Big Game is known as “Super Bowl Squares.” A group game well-known in offices and watch parties, all that is needed to play the game is a 10-by-10 box grid, which can either be drawn or printed out from sources like this.

In the game, each team is assigned either the rows or the columns, and each box will be filled in with a number from 0 to 9. Players then stake claims to one or more of the boxes, depending on the number of participants, either for free or for some amount of money.

The winner of the game is whoever owns the square with the last digit of the winning team's score. Some versions of the game even payout based on the score each quarter.

More in-depth instructions can be found on the Super Bowl’s official website.

While on its surface the game may seem to be up to chance, there is some element of skill and strategy to picking the right number.

One sportswriter noted that based on history and statistics, the winning score at the Super Bowl has ended in four of the last seven Super Bowls and has also been the last number in 28.3% of winning scores in the entire history of the game.

Similarly, seven has been the last number in 24.5% of every winning Super Bowl score. A bet on either of those would appear to be the safest bet.
